JOHN L. LAUGHLIN, OF RAOINE, WISCONSIN.

.CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 274,126, dated March 20, 1883.

' l Application filed August 1,1882. (No model.)

To all whom it may concern Be it known that I, JOHN L. LAUGHLIN, a citizen of the United States, residing at Racine, in the county ofRacine and State of Wiscousin, have invented certain new and useful Improvements in Cultivators, of which the following is a specification.

This invention relates to improvements in oultivators, and has for its object to provide a lo novel constructionof parts for attaching the shovels to their supports, whereby they can be so adjusted as to stand in a plane at right angles to the line of draft, or in a plane obliquely thereto. The manner of accomplishing this will be hereinafter explained in detaihand pointed out in the claims. I attain these objects by the mechanism illustrated in the accompanying drawings, in w hich Figure l is a side view of the shovel-block,

2o sleeve, and the lower end of the shank, all in proper position for work Fig. 2, a view of the same, with the shovelthrownback ward; Fig.3, a view of the back of shovel-block, sleeve, and shank; Fig. 4., a top view of shovel-block and sleeve, with the face of theshovel at a right angle with the shank or line of draft; Fig. 5, a top view of same, with face of shovel inclined; Fig. 6, an enlarged side view, and Fig. 7 an edge view of the sleeve; Fig. Span enlarged 0 side View of the block, and Fig. 9 an enlarged cross-section of the shovel and block through dotted line 0 o in Fig. 3.

Similar letters refer to similar parts throughout the several views.

Attached to the shank D, by a bolt or rivet, G, is a forked sleeve, 0, made of two pieces of metal of equal size and bent to the required shape, and held together at the lower end by a rivet. F. The forked sleeve 0, being hinged at its top to the shank D, is held in place on the said shank D by a break-pin through the hole E. The shovel A and block B are attached to the sleeve 0 by means of a bolt through one of the depth-adjusting holes, H,

5 the edge ofthe sleeve 0 resting against the lugs I I on the block B, and the sleeve (1 being firmly clamped to one of the faces of a wedge-shaped rib, B, raised on the back' of the block B. By means of the said wedge shaped rib on the block B the shovels A A can 0 be carried square on the shank D, or set to throw the furrow either in or out, by changing from one side to the other of the sleeve 0 and bychanging the shovel A from one sleeve 0 to the other. One of the faces of the wedgeshaped rib on the shovel-block B is at a right angle with the face of the shovel A and the other at an oblique angle. A seat for the bolthead is sunk on each face of the rib parallel with the opposite face, as'shown in Fig. 9.

I am awarethat prior to my invention cultivators have been made with adjustable shovels. I therefore do not claim such a combination, broadly; but

What I do claim as my invention, and desire 6 to secure by Letters Patent, is-- V 1. The combination, with the forked sleeve 0, of the shovel-block B, having its front side constructed to form a seat for the shovel, and provided on its back with the rib B, having one of its faces arranged obliquely and the other face at right angles to-the face of the shovel, said rib being detachably secured to the lower end of the forked sleeve, whereby either face of the rib can be secured against 7 5 the said sleeve, substantially as and for the purpose described.

2. The combination, with the shank D and the forked sleeve 0, pivoted at its upper end to the shank and provided with the series of holes E and H, or the shovel-block B, 0011- structed to receive and support the shovel, and provided on its rear with the lugs l, and the rib B, having one ofits faces oblique and the other at right angles to the face of the shovel, substantially. as described.
